3PEAK
Stable 1.3MHz, Precision, RRIO, Op Amps
Description
Features
TP154xA series are CMOS single/dual/quad
op-amps with low offset, stable high frequency
response, low power, low supply voltage, and
rail-to-rail inputs and outputs. They incorporate
3PEAK‟s proprietary and patented design
techniques to achieve best in-class performance
among all micro-power CMOS amplifiers in its
power class. The TP154xA family can be used as
plug-in replacements for many commercially
available op-amps to reduce power and improve
input/output range and performance.
Stable 1.3MHz GBWP Over Temperature Range
Stable 1.3MHz GBWP in VCM from 0V to VDD
0.7V/μs Slew Rate
Only 80μA of Supply Current per Amplifier
Excellent EMIRR: 80dB(1GHz)
Offset Voltage: 400uV Maximum
Offset Voltage Temperature Drift: 1uV/°C
Input Bias Current: 1pA Typical
THD+Noise: -105dB at 1kHz, -90dB at 10kHz
High CMRR/PSRR: 95dB/90dB
TP154xA are unity gain stable with Any Capacitive
load with a constant 1.3MHz GBWP, 0.7V/μs slew
rate while consuming only 80μA of quiescent current
per amplifier. Analog trim and calibration routine
reduce input offset voltage to below 0.4mV, and
proprietary precision temperature compensation
technique makes offset voltage temperature drift at

Shutdown Current: 0.2μA (TP1541NA)
Single +2.1V to +6.0V Supply Voltage Range
–40°C to 125°C Operation Temperature Range
compensation enables the TP154xA to achieve
„THD+Noise‟ for 1kHz/10kHz 2VPP signal at -105dB
and -90dB, respectively. Beyond the rails input and
rail-to-rail output characteristics allow the full
power-supply voltage to be used for signal range.
ESD Rating:
Robust 8KV – HBM, 2KV – CDM and 500V – MM
This combination of features makes the TP154xA
ideal choices for battery-powered applications
because they minimize errors due to power supply
voltage variations over the lifetime of the battery and
maintain high CMRR even for a rail-to-rail input
op-amp. General audio output, remote battery-
powered sensors, and smoke detector can benefit
from the features of the TP154xA op-amps.
Green, Popular Type Package
Applications
Audio Output
Active Filters, ASIC Input or Output Amplifier
Portable Instruments and Mobile Equipment
Battery or Solar Powered Systems
Smoke/Gas/Environment Sensors
Piezo Electrical Transducer Amplifier
Medical Equipment
For applications that require power-down, the
TP1541NA in popular type packages has
a
low-power shutdown mode that reduces supply current
to 0.2μA, and forces the output into a high-impedance
state.
